Dosage

Children: Refer to specific acid formulations and guidelines for dosing. General dosing depends on the acid and its clinical use.

Adults: Refer to specific acid formulations and guidelines for dosing. General dosing depends on the acid and its clinical use.

Mechanism of action

Acids exert their effects primarily by dissociating into protons and anions in solution, thereby lowering the pH of the surrounding environment. This proton donation can influence various physiological processes, including enzyme activity, ion transport, and cellular signaling pathways. For example, hydrochloric acid in the stomach aids in digestion and the absorption of certain nutrients.

Pharmacodynamics

The pharmacodynamic effects of acids are largely dependent on their concentration and the specific type of acid involved. Weak acids may dissociate partially, leading to a less pronounced effect, while strong acids fully dissociate, leading to significant changes in pH and potential tissue irritation. Acids can also interact with various receptors and enzymes, influencing metabolic pathways and physiological responses.

Pharmacokinetics

The pharmacokinetics of acids vary widely depending on their chemical structure. Strong acids, such as hydrochloric acid, do not significantly enter systemic circulation due to their rapid dissociation in aqueous environments. Weak acids may be absorbed through the gastrointestinal tract, where their absorption is influenced by pH, solubility, and the presence of food. Metabolism and excretion pathways also vary, with some acids being metabolized to bicarbonate or other metabolites before excretion, primarily via the kidneys.

Mechanism of action

Buffered medications work by neutralizing gastric acid, aiming to maintain a more neutral pH in the stomach or gastrointestinal tract. This action can facilitate better absorption of certain drugs that may be degraded or poorly absorbed in acidic environments. The buffering agents typically include compounds such as sodium bicarbonate or magnesium hydroxide, which react with gastric acid to decrease acidity.

Pharmacodynamics

The pharmacodynamic effects of buffered medications depend on the active pharmaceutical ingredient, but the buffering agents primarily function to mitigate the acidity of the stomach contents. This can lead to reduced irritation of the gastric mucosa and enhanced comfort for the patient. The overall effect is to promote a more favorable environment for drug absorption and decrease potential side effects associated with high acidity.

Pharmacokinetics

The pharmacokinetics of buffered medications can vary based on the specific active ingredient used. Generally, the buffering agents do not significantly alter the absorption, distribution, metabolism, or excretion of the drug but serve to improve solubility and stability. The onset of action may be faster for some formulations due to improved absorption in a less acidic environment. The buffering agents themselves are typically rapidly absorbed and excreted by the kidneys.

Pregnancy

Safety during pregnancy has not been established, consult healthcare provider before use.

Breast-feeding

Dosage

Children: For children over 1 year of age, the recommended dosage of activated charcoal is 1 gram per kilogram of body weight, up to a maximum of 50 grams. For children under 1 year, consult the BNF for Children for specific dosing guidance.

Adults: The usual adult dosage for activated charcoal in the treatment of poisoning is 50 to 100 grams, administered orally or via a nasogastric tube. Repeat doses may be given in certain cases, depending on the toxin involved.

Mechanism of action

Activated charcoal works primarily by adsorbing toxins and drugs in the gastrointestinal tract, reducing their systemic absorption. The extensive surface area and porous structure of activated charcoal allow it to bind various substances through van der Waals forces and hydrogen bonding. This binding action helps to prevent the absorption of harmful substances into the bloodstream, facilitating their elimination from the body.

Pharmacodynamics

The efficacy of activated charcoal is related to its ability to adsorb a wide range of substances, including many pharmaceuticals and poisons. The effectiveness can vary depending on the specific substance, the timing of administration, and the dose of activated charcoal. It is generally most effective when administered soon after ingestion of the toxin.

Pharmacokinetics

Activated charcoal is not absorbed systemically; it acts locally within the gastrointestinal tract. After administration, it passes through the gastrointestinal system and is eventually excreted in the feces. The adsorption capacity of activated charcoal is influenced by factors such as the surface area, particle size, and the nature of the toxin to which it is exposed.
